Specification of Letters Patent.

Patented Nov. 14, 1916.

Application filed April 4, 1914. Serial No. 829,555.

To all cli/wm t may concern Be it known that I, GEORGE C. SNYDER, a citizen of the United States, residing in the city of New York, county of New York, and State of N ew York, have invented certain new andiuseful lmprovements in Fastening Devices; and l do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to fastening devices of the same general type as those disclosed in my pending applications, Serial No. 790,236, filed September 17, 1913; Serial No. 13,492, filed October al, 1913; and Serial No. 817,814, filed February 10, 1914, but involving the improvements hereinafter set forth.

In theapplications above referred to, different forms of fasteners are described, in

which the fabric to which the fastener is secured is clamped in an annular space formed by co-aXial inner and outer' members.

The present improvement consists more particularly in the novel formation of the inner member to permit the same to be readily expanded or spread into fabric clamping relation with the walls of the outer member with which said inner member is co-axially positioned.

rThe invention is illustrated in the accompanying drawing, which illustrates the invention as applied to buttons, but it will be obvious that the invention is equally applicable to fasteners of other types.

In the drawing, Figure 1 is a top plan view of the improved fastener; Fig. 2 is a vertical section of the button shown in Fig. 1, taken on the line 2-'2 of Fig. 1; Figs. 3, a and 5 illustrate the successive steps involved in assembling the fastener; Fig. G is a vertical section showing the application of the invention to a button of the solid type; Fig. 7 is a vertical section showing H the use of a protective disk applied tothe opening in the face of the button, serving to protect and to conceal the fabric forced into the opening of the button by the inner member; and Figs. 8 and 9 are vertical sections involving the use of a modified form of inner member.

Referring more particularly to Figs. 1, 2, 3, a and 5, the fastener, in the present instance, consists of a button having the head portion 1 and a tubular shank 2. The button disclosed in these figures is of the metal type, and the shank 2 is formed integral with the head portion 1. rhe base of the shank is provided with a clamping flange for thepurpose hereinafter described. As shown in the drawing, the inner walls of the shank 2 taper toward the base of the button, and it is this tapered shank of the button or its equivalent which constitutes the outer member herein referred to. The inner member, in the form disclosed in Figs. 1, 2, 3, l and 5 consists of an eyelet a, preferably formed of a soft or plastic material., and involving a central opening 5 and a clamping flange G adapted to coperate with the flange 3 of the button 1 to clamp the fabric to which the button is secured. As shown in Fig. 3, the eyelet before assemblage has substantially parallel outer walls, but the walls of the opening 5 taper outwardly toward the ange 6, so that the walls of the eyelet are thicker at that end of the eyelet remote from the flange 6, than at that point where the fiange 6 joins the walls of the eyelet.

1n assembling the button and attaching the same to a fabric, the latter is stretched over the flanged end of the button shank 2, shown in Fig. 8, and the eyelet i is placed in alinement with the opening in said shank 2, and with a suitable assembling tool 7. As said tool 7 descends, a pointed extremity S thereon perforates the fabric, and a tapered portion 9 thereof forces the eyelet i into the shank 2 of the button carrying with it the fabric a.. As the tool 7 further descends from the position shown in Fig. at to that shown in Fig. 5, the spreading surface 9 serves to spread the inner walls of the eyelet Je into parallelism, as shown in Fig. 5, thereby spreading the outer walls of the eyelet into substantial parallelism with the tapered walls of the shank 2 of the button, and thus firmly and tightly gripping the fabric in an annular space defined by the outer walls of the eyelet f1 and the inner walls of the shank The button is, therefore, assembled by a single stroke of the tool 7, which carries the eyelet 4 downwardly until the flange 6 thereof abuts the flange 3 of the button 1, and then the further movenient of the tool 7 spreads the eyelet, as just described. The fabric is, therefore, not only clamped in the annular space referred to, but is also tightly gripped and clamped between the flanges 3 and 6 of the button and eyelet, respectively.

In Figs. (i, 8 and V9, a modified form of eyelet is disclosed, and in Fig. 6, the eyelet is used in combination with a button of the solid type, but it is obvious that the eyelet heretofore described may also be used in combination with a button of this description. Referring to Figs. 8 and 9, the button disclosed is of the same type as that de scribed in connection with the other figures, but the eyelet, instead of being of greater thickness at its end remote from the clamp ing flange, than at its end provided with said flange, is provided with an out-turned flange l0, the external diameter of which is substantially the same as the external diameter of the eyelet in'imediately adjacent the flange (5. The inner walls of the open ing 5 of the eyelet taper, as in the form previously described, and as the tool 7 descends in the manner hereinbefore set forth, it is obvious that the eyelet will be spread in exactly the same manner as before. As shown in Fig. 9, however, the fabric, instead of being clamped throughout the length of the body of the eyelet, is clamped between the flange i0 and the walls of the shank 2. In both forms, however, it will be noted that the external diameter of the eyelet, at a point remote from the flange 6, is greater after assemblage, than the external diameter of the eyelet immediately adjacent the iiangeG. The fabric is, therefore, not only'rmly clamped and gripped in an annular clamping space, ,and between the flanges 6 and 3 by the novel formation of the eyelet, and the mode of assembling the same with the button, but after assemblage, the eyelet is tightly and firmly interlocked with Y the button.

In the form shown in Fig. (S, in which a solid button l is employed, the base of the shank 2 thereof performs the same function as the clamping flange 3 of the metallic button. In order to prevent the edge `ortion of the shank 2 from cracking under the expansive force of the tool 7, the upper portion of the shank is preferably bound around its edge by a thin metal binding 1l.

In order that the buttons may present a more finished appearance, they may be covered withany appropriate material 19, as shown in Figs. 3, 4 and As the eyelet carries the Vmaterial with it into the shank of the button, a portion o-f the fabric will be visible in the opening of the button, as indicated atl in Figs. 2 and 9. In order to conceal this portion of the fabric, and to protect the same and to give a more nished ap pearance to the button, a disk 14, (Fig. 7),

may be forced into the opening of the batton, as clearly shown 1n the drawing.' in which the disk 14 1s shown in dotted lines' before the same is positioned, and in full lines after the same has been applied to the button. It is obvious, however, that the bntton maybe covered or finished olf in any desired manner to present a neat appearance, this feature being immaterial, so far as the present invention is concerned.

By shaping the eyelets, as hereinbefore described, the fastening device may be attached to the fabric in a single operation, and in an extremely simple manner, and the fabric may be tightly gripped not only between the clamping flanges of the eyelet and button, but also in the annular clamping space heretofore described, so that the fastening device is securely and firmly attached to the fabric, thereby precluding all danger of the fabric pulling loose from the fastener, which is sor objectionable in other types.

What I claim is:-

l. A fastening device comprising an outer member havingan opening therein with its inner *alls tapering toward the base cf said member, and an eyelet adapted to beplaced in co-axial relation with the opening in said outer member and having` at its base a flange adaptedl to clamp the fabric to which the'device is secured to the base of said outer member, said eyelet provided with a central opening passing completely therethrough of greater diameter at the base of the eyelet than at tl e top thereof, the walls of said eyelet opening adapted to be spread linto substantial parallelism to increase the external diameter of the top of the evelet and thereby clampv the fabric in an annular space between the eyelet and the Yalls of ther opening` of the outer member. n

2. A fastening device comprising a button having an opening therein with its inner walls tapering toward the base of said button, and an eyelet adapted to be placed in co-aXial relation with the opening in said button and having at its base a flange adapted to clamp the fabric to which the device is secured to the base of said button, said eyelet provided with a central opening passing completely therethrough of greater diameter at the base of the eyelet than at the top thereof, the walls of said eyelet opening adapted to be spread into substantial parallelism to increase the external diameter of the top of the eyelet and thereby clamp the fabric in an annular space between the eyeA -let and the walls of the opening of the button.

In testimony whereof I aliix my signature, in presence of two witnesses.
